Question

If someone could explain the equation so I can answer the rest that would be amazing! A stone statue is 15 meters tall. A model of the statue was built with a scale of 1 cm : 5 m.

How tall is the model?
A. 75 cm
B. 10 cm
C. 3 cm
D. 15 m

Answer 1

C) 3cm

Explanation:

this is a ratio, and ratios always have to be constant meaning there is a pattern. for 15 meters to become 5 what must happen? dividing by 3.

1:5 ?:15 you dont know the ? but you do know what it becomes after divided by 3. so multiply 1 by 3 to do the reverse.

comment if you have more questions!

Answer 2

Answer: 3 cm

Work Shown:

(1 cm)/(5 m) = (x cm)/(15 m)

1/5 = x/15

1*15 = 5*x ... cross multiply

15 = 5x

5x = 15

x = 15/5

x = 3

The model is 3 cm tall.
